- Description

Abstract: Frequent surveys using modern remote sensing technology enable observations of subaerial beach morphology and surface sediment type (sand versus gravel/cobble) with unprecedented spatial and temporal resolution. Here we show weekly terrestrial mobile LiDAR observations of cusps on a mixed sediment beach, consisting of sand and gravel/cobble, spanning ~2 km alongshore. Surface gravel/cobble coverage varied from almost complete to none (e.g. all sand), over times ranging from weekly to seasonal, and with location. Cusp morphologies also varied in space and time. Cusps with 11-20 m alongshore wavelengths (L) primarily developed in winter and were composite with gravel-cobble horns and sandy bays. Cusps with L between 21-40 m developed throughout the year and were either composite or entirely sandy. Previously not reported, composite mega cusps (L between 200-400 m) occurred in winter. Composite cusps, with L between 11-40 m, were clustered in gravel/cobble-rich mega cusp bays, and absent on the sandier mega cusp horns.
